Web ASP.NET AJAX
Common reasons for the ‘Sys is undefined’ error in ASP.NET Ajax applications
In this blog I will try to summarize the most common reasons for getting the famous 'Sys is undefined' error when running an Ajax enabled web site or application (there are almost one million results on Google for that phrase). Where does it come from? In every Ajax web page’s source you will see a code like this: <script type="text/javascript"> //<![CDATA[ Sys.WebForms.PageRequestManager._initialize('ScriptManager1', document.getElementById('form1')); Sys.WebForms.PageRequestManager.getInstance()._updateControls([], [], [],...March 16, 2010

Silverlight Recruiting Application Part 4 - Navigation and Modules
After our brief intermission (and the craziness of Q1 2010 release week), we're back on track here and today we get to dive into how we are going to navigate through our applications as well as how to set up our modules. That way, as I start adding the functionality- adding Jobs and Applicants, Interview Scheduling, and finally a handy Dashboard- you'll see how everything is communicating back and forth. This is all leading up to an eventual webinar, in which I'll dive into this process and give a honest look at the current story for MVVM vs. Code-Behind applications. (For...March 15, 2010

RadBook now supports virtualization
I am proud to announce that RadBook, along with RadGridView, RadTreeView, RadTreeListView, RadChart and RadScheduler, now supports virtualization. With previous versions, it would take up to 16 seconds to load 1000 pages, where now it takes just 2 seconds to load a set of 10,000,000 (10 million) items. The cause of the performance boost is the way RadBook handles the unnecessary(non-visible) elements.

Previous versions of RadBook would just collapse the unnecessary elements, which had a significant impact on the initial loading time. The...March 12, 2010 -

Silverlight Recruiting Application Part 3.5 - Prism Background and WCF RIA [Series Intermission]
Taking a step back before I dive into the details and full-on coding fun, I wanted to once again respond to a comment on my last post to clear up some things in regards to how I'm setting up my project and some of the choices I've made. Aka, thanks Ben. :) Prism Project Setup For starters, I'm not the ideal use case for a Prism application. In most cases where you've got a one-man team, Prism can be overkill as it is more intended for large teams who are geographically dispersed or in applications that have a larger scale than my Recruiting...March 06, 2010
